Renewable Energy Filters

These new three phase filters from Premo require no neutral line and are especially suitable for renewable energy applications such as those experienced in wind generation

Renewable energy sources are now becoming an ever-growing alternative to generating electricity by conventional methods which give out potentially harmful environmental pollution. This is certainly not the case with the increasing use of power generation through wind turbines. However, the power injection into the grid network must be executed cleanly; this means that the power generated must be radio frequency (RF) noise free.
The radio frequency noise that typically ranges from 10kHz to 30MHz can be unintentionally injected into the grid network and therefore requires the use of an appropriate filter element which includes the desired frequency range attenuation and also the ability to handle safely the current capacity required.
Premo has developed its HCWMGF-series of filters for applications in renewable energy equipment, UPS, inverters and power inverters, with a maximum operating voltage of up to 720Vac.
Main characteristics:

The HCWMGF series is available in a three phase version L1, L2, L3 (without the need for a neutral line) with ratings from 150A to 2500A, delivering extremely low power losses of less than 0.02%.
Premo EMC has a long experience in the development of filters in both DC and AC single and three phase, and all PREMO filters have been developed taking into account the specific needs of the application they are intended, in terms of attenuation levels, volume, weight, connections, mechanical shape, etc.
In collaboration with development centres, universities, suppliers and customers, Premo has incorporated into its design many industry-leading innovations and new magnetic materials to provide results that fully meet customer needs and requirements in this new and demanding area of renewable energy generation.
Premo EMC has a fixed and a mobile laboratory for EMC testing machines / facilities for its customers and ensures EMC solutions for compliance with specific regulations to be applied.
